Autism spectrum behaviors and social information processing in Rett syndrome,

Angelman syndrome, and MECP2 duplication syndrome

This is a research study about brain/behavior relationships in MECP2 duplication syndrome. We are interested in assessing features of autism and, if these are present, how they related to brain functioning and clinical profiles.

As part of this study, we will do a psychological assessment of your child’s development and behavior. Using an EEG cap that will be placed on your child’s head (not stuck) we will have him look at photos of people with different facial expressions on a computer screen while we track his brain wave responses to these photos. Also, while wearing the EEG cap, we will track your child’s brainwave responses to a recording of your voice saying “hi,” contrasted with a recording of unfamiliar voices saying “hi.” Finally, we will have your child look at a photo of you on a computer screen and track the movement of his eyes across your face, and contrast this with a photo of an unfamiliar person while also tracking the movement of his eyes and scanning patterns. We will additionally have you complete forms about your child’s behaviors and sensory interests/aversions. You will receive a report of your child’s developmental abilities at no cost.

The total time for this appointment is approximately ½ day or 4 hours.

We are seeking participants between the ages of 3 and 12 years old. Dr. Sarika Peters is in charge of the study which is funded by a Hobbs Discovery grant through the Vanderbilt Kennedy Center at Vanderbilt University in Nashville, TN.

Taking part in this study is voluntary. You may choose not to take part in the study. You are free to withdraw at any time, and there is no direct benefit for you participating in this study. Your decision will not change any present or future relationships with Vanderbilt University or its affiliates or other services you or your child are entitled to receive.
